Non-legacy contamination by 3,3'-dichlorobiphenyl in marine species: comparison between Mediterranean area and Antarctic region
Polychlorinated biphenyls (PCBs) are among the main classes of persistent organic pollutants (POPs) and are largely distributed in every environmental compartment worldwide. The sources of PCB contamination are commonly associated to the industrial use of commercial mixtures, such as Aroclors, which...

Polychlorinated biphenyls (PCBs) are among the main classes of persistent organic pollutants (POPs) and are largely distributed in every environmental compartment worldwide.
